The Onyx Series is built of 50 x 100 mm heavy-gauge flat oval steel tubing. To ensure long-term protection against high-traffic abuse, the frame is protected by a high-quality, chip-resistant, two-coat electrostatic powder finish.
The Onyx Series isolates targeted muscle groups using 5 mm-coated steel cables that move over glass-fibre-reinforced nylon pulleys. These pulleys feature deep V-grooves for flawless cable seating and premium bearings for perfectly silent, frictionless rotation.
All selectorised stations are designed with highly visible, colour-coded, quick-release seat-adjustment levers. The interaction points feature precise, laser-numbered positions so athletes can seamlessly repeat their ideal ergonomic settings.
Absolutely. Every machine in the Onyx lineup is wrapped in full-length front and rear safety shrouds. This completely encloses the black painted steel weight plates and low-friction sleeves, keeping dirt, debris, and hands out of the moving stack.
The Onyx range provides strict, anatomically sound movement tracks for both single and dual-function profiles. Notable models include the standard Chest Press (OSCP 100kg stack), the Pec Fly/Rear Delt dual platform (OSFLY), the Prone Leg Curl (OSPLC), and specialised extensions like the Standing Calf (OSSCE).
